Official observations from Los Angeles International Airport (KLAX) recorded a daily high near 79°F on July 31 under clear skies and light winds, driving the market's 100% implied probability on the 78-79°F outcome. National Weather Service climatological reports and station data confirm this value, consistent with regional atmospheric stability that limited daytime heating compared to earlier heat-dome forecasts for the period. Historical July averages at coastal stations hover around 75-80°F, providing climatological context for the result. Resolution hinges on the designated official station and daily maximum criteria, so minor reporting adjustments or alternative station readings represent the primary scenarios that could shift the outcome despite the strong current consensus.
